WITNESSES W ZINVENTORI 'Arronr also to dry the solid residue. The. head 46 at the other end of the tank is connected to a union having a member 47 which is connected by a pipe 48 with the conduit 21: a member 49 which is connected by a pipe 50 with the chamber 22, and a member 51 which is. journaled in a stufling box 52 from which leads a pipe 53. The pipe 48 has a valve 54 and the pipe 50 has a valve 55. In the use of this particular embodiment of the invention for the extraction ofthe oily and fatty contents of garbage, fish or animal tankage, for example; the container 10 is turned to a position wherein its chamber 22 may be conveniently supplied with the material to be treated through the manholes 17.

The manhole covers 18 are tightly closed when the container has been charged with said material. WVith the valves 37, 45, 29 and 54 closed, and valves 36, 38,'and-31 open, naphtha, or other solvent used is pumped into the treating chamber 22 from its source of supply, not shown, reaching said chamber way of the pipes 33, 35, 40 and 30. After the material in the chamber 22, has undergone treatmentthe required length of time, the valves 36 and 31 are closed and the valves 37 and 29- are opened, the other valves remaining as before. The treating fluid and the extractedmaterial are now drawn from the container, the material which has settled in the conduit 21 reaching the collecting tank (not shown) by Way of pipes 28, 40,

and 34 and the material 'WhlCll is in the treating chamber 22 of treating chamber 22 being drawn into said conduit through the perforations and thence h. said pipes.-

passing to said tank throu When this'step in the operat on of the machine has been completed, valves29 and 38 are closed and valves 45, 31 and 54 are opened. Steam will now be supplied to the the tank, through the pipes 44, 40 and 30 said steam, together with the-oily has extracted from the material undergoing treatment, and also the treating fluid recovered by said steam leaving said chamber 22 by way of the perforations 20, conduit 21,-

pipe 48 and 53 to a separating tank or condenser not shown. The last step of the operation may be continued until all' the treating fluid has been recovered'and the material undergoing treatment has been reduced to a dry and solidmass.

When the solvent naphtha isbeing sup plied to the container, the air valve 55 is opened to permit the air-to escape from the container. \Vhen' theair has escaped this I valve is preferably closed, a safety valve 56 on one of the manhole co'vers 18 serving to prevent too high a pressure in the container. This valve 55 is also open-while the extracting fluid as naphtha is being with drawn from the tank container to prevent vacuum. .At the end of the operation, the

and fatty -matters which itterlal in a comparatively loose condition, so

that the treating fluid may most effectively reach all parts thereof. It will be .noted that the co-relation of the pipes to each other and to the container is such that the flow of the fluids into and outvfrom the container through said pipes is not prevented while the container is being turned.

In the particular embodiment'shown in Figs. 1 and 2, the pipes 28 and 48, as are all the other pipes, are shown as being entirely outside the container and as o ening into the containerthrough the wall of the latter. This is a preferable arrangement for the reason that it leaves the interior of the container unobstructedby any pipes. Butany or all ofthe pipes may extend into the container if desired, withoutdeparting from the spirit of the invention. This is particularly true with reference to the .pipes (as 28 and 48) which 'open into the chamber or conduit 21. Thus, illustrating this with reference to the pipe through which the cleansing and drying fluid flows from the container, which pipe is designated4S in Fig. 1 and is therein shown as being outside the container having its inlet at the ,wall of the latter, the corresponding element of Fig.

3, namely thepipe marked 48 may be disposed within the containerwith its'inlet'at the perforated wall or plate 19;while'in ig. 4, the corresponding pipe, marked 48" is partly outside of the container and has a branch, 48which extends through the ad.-

jacent head of the latter at a place near the perforated wall 19, said branch-having the inlet for the pipe at said perforated wall or plate. Moreover, the pipe 50 may be disposed with, if desired, as indicated in Fig. 3, and many other changes in the details may be made, as is apparent. 7

From the foregoing it will be seen that I have PIOXidQd ail-apparatus of maximum efficiency for the purposes for which it is intended -to be used, the co-relation of the parts being such that the treating fluid; may be used in an effective manncrand are delivered toand from the tank through a most simple system of pipes.

Having now described the invention, what I believe tobe new and; desire to secure by Letters Patent, is: i

In witness whereof I lune hereunto set my hand at the city county and State of New York, this first day of August, 1911.
